GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
Where Does Peristalsis Occur. Peristalsis occurs throughout the digestive tract. It begins with the primary peristaltic wave in the esophagus as you swallow food from your mouth to the stomach.As food enters your stomach these muscular movements continue right through to your anus, where waste is eliminated from the body.n simplistic terms, it means moving food and liquids within the body from one place to another. These rhythmic, wave-like movements are created by peristaltic muscle contractions which are located within the walls of your digestive tract.
